Easily identified at-risk patients for extubation failure may benefit from noninvasive ventilation: a prospective before-after study

Background While studies have suggested that prophylactic noninvasive ventilation (NIV) could prevent post-extubation respiratory failure in the intensive care unit, they appear inconsistent with regard to reintubation. We assessed the impact of a prophylactic NIV protocol on reintubation in a large population of at-risk patients. Methods Prospective before-after study performed...

New-onset supraventricular arrhythmia during septic shock: prevalence, risk factors and prognosis

Background The aims of this study were to prospectively assess the prevalence of sustained (lasting more than 30 s) new-onset supraventricular arrhythmia (NOSVA) during septic shock, identify the associated factors (including septic myocardial dysfunction), and evaluate its impact on hemodynamics and prognosis. Methods Patients with a diagnosis of septic shock were screened in a...

Severe but not mild hypercapnia affects the outcome in patients with severe cardiogenic pulmonary edema treated by non-invasive ventilation

Background Patients with severe cardiogenic pulmonary edema (CPE) are frequently hypercapnic, possibly because of associated underlying chronic lung disease (CLD). Since hypercapnia has been associated with outcome, we aimed to identify factors associated to hypercapnia and its role on outcome of patients with CPE and no underlying CLD. Methods Observational cohort study using...

Echocardiographic detection of transpulmonary bubble transit during acute respiratory distress syndrome

Background Transpulmonary bubble transit (TPBT) detected with contrast echocardiography is reported as a sign of intrapulmonary shunt during cirrhosis or exercise in healthy humans. However, its physiological meaning is not clear during acute respiratory distress syndrome (ARDS). Our aim was to determine the prevalence, significance, and prognosis of TPBT detection during ARDS...

Non-invasive ventilation for acute hypoxemic respiratory failure: intubation rate and risk factors

Introduction We assessed rates and predictive factors of non-invasive ventilation (NIV) failure in patients admitted to the intensive care unit (ICU) for non-hypercapnic acute hypoxemic respiratory failure (AHRF). Methods This is an observational cohort study using data prospectively collected over a three-year period in a medical ICU of a university hospital. Results Among 113...
